Chlorine is more reactive than bromine, thus it displaces bromine.
<span>This can be solved using basic algebra. X equals the number of liters of 2% brine to add. Therefore we use this equation. 3 + 0.02x = 2.4 + 0.08x 0.6 = 0.6x x = 0..6/0.06 x = 10</span>
Alloys are supposed to give greater strength to metals, which is why gold is mixed with others to make it harder. They have greater strength and are more resistant to erosion.
